Title: Sulphur dioxide removal from gases - by absorbing in soln. contg. a metal halide and hydroxide
Inventor: FURUTA ISAO
IPC: C01F11/46
Filed: 1976-12-21
Abstract: Process of parent patent is for removing S, esp. SO2, from a gas by contacting with an absorbant soln. contg. 25-33 wt.% of a halide of a metal from Groups II, III, and VIII and 0.3-0.8% of a hydroxide of the metal. In the addn. the compsn. range of the halide is increased to 7.5-36 wt.% and the lower compsn. of the hydroxide is decreased to 0.03% without affecting the efficiency. The soln. may be clear or limpid rather than a paste. The CO2 absorption capacity of the soln. can be reduced with CaCl2 and the desulphurisation efficiency increased. Solids can be easily separated from the soln. Compared with the limestone-gypsum process a higher rate of SO2 removal is possible for the same pH. NO2 can also be removed.

Title: Roller test bed for vehicle operating factor measuring - has slip correction circuit measuring wheel and roller rates
Inventor: DINKELACKER WALTER DIPL PHYS
IPC: G01M15/04
Filed: 1978-11-25
Abstract: A rolling test bed is used to measure vehicle operating factors including engine efficiency. The vehicle wheels rotate on the test rollers whilst the power at the wheels is measured using a correction factor dependent on traction force related losses, i.e. on the slip between wheels and rollers. If the slip increases beyond a certain value the engine loading is reduced. The slip dependent factor is determined from a comparison of the loaded and unloaded ratios of the rates of revolution of the roller and the engine or the wheel. The ratio of wheel to roller revolution rates as determined by a divider is stored. A subsequent divider output and the stored value are fed to a further divider whose output gives an indication of the slip.
Patent DE-2912434-A1 (DE)
Title: Attenuator for RF signals with three PIN diodes - has diodes interconnected and biased to attain high reflection attenuation and high isolation
Inventor: ENGLERT REINER
IPC: H03H7/25
Filed: 1979-03-29
Abstract: The attenuator has three PIN diodes (13, 16, 19) forming a PI-network. The impedances in the series and parallel paths of the network are adjusted by altering the currents such that the impedances are opposing--ie the series impedance increases as the parallel impedance decreases for the same current (and vice versa). A voltage divider (10) sets the voltage at both parallel PIN diodes (13, 16). One of these two diodes is dc - decoupled by a capacitor (18) from the series PIN diode (19). The voltage at the node between the capacitor and the series PIN diode is also set via voltage divider. The current branching at the node between the PIN diodes (19, 16) thereby causes an opposing change in the impedances.
